Mr and Mrs Milton Buck
The man is my 2nd great uncle Milton Buck. His mother(Winifred Buck) took this picture. I believe it is with his first wife Isabel Buck (Whitfield ). Milton was also married to Gladys Irene Buck (Kisner) and Mary Arlene Buck (Eggenschwieger). It is one of those women for sure. My guess it is Isabel.
The picture had to be taken prior to November 15, 1937 my 2xgrandmothers death.
